3.Quality standard

GB/T 3875-2006 (tungsten plate)

As a high performance materials, pure tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity.

Tungsten sheets and disk are available with alkali washed or ground finish. 

4.Application

Tungsten has a unique property of which it's melting point can reach 3410 tungsten,is widely applied in high temperature vacuum furnace melting environment such assapphire growing furnace, quartz glass melting furnace, and rare earth melting furnace. For sapphire crystal growing furnace, high purity, high density, no crack,tungsten crucible with other features of exact measurement and smooth surfacehas decisive influence on the success of crystal growth, quality control of pulling crystal, discharging and service life during sapphire growing.
